FLUE-THIMBLE PROTECTOR.

To all iti/0m 'it may concern Be it known that I, Vieron WESTERLUND, a citizen of the United States, residing at lortland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Flue-Thimble Protectors, ot' which the following is a specification.

This invention pertains to iiue thimble l protectors, and has for its object to provide a device which may be secured about the thimble of a flue to receive the plaster, and which carries a movable elementtted upon the thimble, permitting the latter to move to a limited extent without disturbing the plaster orinjuring the thimble. v

A further object is to provide in a device ot' the kind indicated a movable element which may be fitted upon thimbles of different types, and which will permit the thimble to move the usual distance in settling.

I accomplish't-hese objects by means of the structure illustrated in the accompanying drawing, in which` Figure l is an elevation of the device showing the movable element at its upper limit. Fig. 2 is a vertical sectional view taken on the line X-X of Fig. 1.

Describing the drawing in detail, 1 designates a sheet metal plate, in which there is formed a. central oblong aperture 4, adapted to expose the Hue opening when the plate At each of the four sides of the plate is formed an extension, 0r Wing 2; and each of these wings is folded inwardly at 3, and again bent outwardly to stand in a plane parallel with portion. The first fold 3 is doubled back beyond the point of bending; and the terminal portion fisagain bent outwardly to t'orm a retaining element to lie flat upon the laths S) to which they are nailed.- This leaves a channel 3*l into which the plaster 8 will be forced to form a retaining bead and leaving the plaster flush with the outer face of the plate. There is thus formed about the inner edge of t-he plate l aslide way to l receive the movable plate 5. This plate may be secured in position by first f ding the wings at three of the sides and then inserting plate 5 at the open upper or lower edge, after which the remaining win will be folded to complete the plate 1. T e plate ,5 is adalpted to rest against the outer end of the ue thimble 6 which extends from the Specification of Letters Patent. Application sied october 22, 191s.

chimney to a point slightly within the face of the plastered wall, and it has a central opening registering with the o ening of the flue thimble. iVithin this opening is formed a tubular flange like portion 5n which fits l neatly in the projecting portion of the thimi l ble, and extends preferably into the chimnev.

Ith'e thimble and forms a closure for the opening 4 of the plate l.

As the building shrinks and settles about the chimney the outer late will move'downwa'rdly about the thim le, thus causing plate 5 to move upward relatively, in its slide way, and relieving the thimble and the plaster of the strain which so frequently destroys them:

The plate 5 will be of a width that will permit it to move in plate 'l a distance equal to the probable amount of shrinkage, and it is also made with a view to keeping the opening 4 closed during such relative movement. The engagement of the tubular portion in the. thimble holds the plate 5 fixed with reference to it, preventing its displacement and preserving a neat appearance.

The extent of the oblong opening 4 will be determined by the amount of settling that if: likely to occur, and when the settling of the building is complete, the slide plate 5 willst-and at its upper limit as seen in F ig. l. It, of course, will be left at its lower limit, on completion of the building.

It is obviopsthat the tube 5a may befa separate piece and not formed integrally as shown. Y

Having thus described my invention, what I claim, is-

1. A fine thimble protector comprising a main plate having a central oblong opening, a wing extending from each side of the plate and bent inwardly t0 form a track, each wing being then bent outwardly to form a channel, leaving their edges exposed, and a plate having a thimble engaging means slidably secured in said tracks.

2. A flue thimble protector comprising a main plate having a central oblong opening, a wing extending from each side of the plate and bent inwardly to form a plate retaining flange, whence they are bent outwardly to form a base for said plate, leaving a plaster engaging channel, and a thimble engaging plate slidably secured within the plate retaining flanges.

3. A Hue thimble protector comprising a This holds the plate 5 in place over aplaster. engaging channel, a plate having main plate having a central oblong opening, a Wing extending from each side of the plate and bent inwardly to, 'orm a plate retaining ange, whenee they are bent outwardly to form a base for said plate, leaving ment secured in the aperture of the sliding le plate adapted to 'engage in the ue thimble,
